TYPE FOR PRINTING LAMP-SHADES.

SPECIFICATION forming part of Letters Patent No.,453,7'70, dated June 9,1891. Application filed August 20, 1890- Serial No. 362,496. (No model.)

To aZZ whom it may concern:

Be it known that I, THOMAS HARPER, a citi zen of the United States, anda resident of Vestchester, in the county of Vestchester and State of NewYork, have invented certain new and useful Improvements in Type forPrinting Lamp-Shades and Analogous Articles, of which the following is aspecification.

The object of my improvement is to provide simple and inexpensive typewhich will present a substantially flat surface for inking and willyield to adapt itself to the convexity of a lamp-shade or like article.

I will describe type embodying my improvement, and then point out thenovel features in the claims.

In the accompanying drawings, Figure 1 is a face view of a typeembodying myimprove- Inent. Fig.2 is a back view thereof. Fig. 3 is aside view of the same.

Similar letters of reference designate corresponding parts in all thefigures.

Referring by letter to the accompanying drawings, A designates theprinting-surface of a type. It will preferably be made of rubher orrubber cloth.

B designates a support for the printingsurface, consisting of a mass ofyielding composition such, for example, as that employed for thesurfaces of the inking-rollers in printing-pressescomposed of glue,glycerinc, and molasses. This composition, as shown, is made in the formof a block, which is fastened at the back to a sheet B of indiarubber,rubber cloth, or like elastic material. The composition forming thesupport B may be secured to the sheet 13 throughout its entire backsurface or only at one or more points,

as may be preferred. I deem it advantageous to fasten theprinting-surface A to the support B only at the center, as then it andthe support 15 will be more free to adapt themselves to the surfaces tobe printed. The printingsurfaces may be secured to the support B and thelatter to the sheet B by means of any suitable cement, as at s, Fig. 4.The sheet B is shown as secured to a frame composed of strips C C C (lof sheet metal. The end portions of these strips cross each other andare longitudinally slotted. Through their slots pass screws 0', whichengage with tapped holes in the ends of the arms 0, com prised in aholder 0. The screws 0 do not clamp the strips C C) C O to the arms 0,but leave them loose, so that they can slide longitudinally and alsobend to allow the sheet B to bend, so as to conform more or less to theconvexity of surfaces upon which printing is to be done. The sheet 13 isfastened by screws 1) to the strips 0 C C C As here shown, the heads ofthe screws 1) fit in countersunk holes in washers or plates 6 which bearagainst the top of the sheet 13', and have nuts applied to their lowerends beneath the strips C C C C. It will be seen that the arms 0 of theholder 0 extend to the points where the strips C C C C intersect.

C C designate two metallic strips, which cross each other opposite thecenter of the support 13 and have longitudinally-slotted extremities,which receive those screws 1) which are at the centers of the sides ofthe sheet 13. The nuts which are applied to these screws secure thestrips G 0 to the strips 0 O C 0 but form aloose connection betweenthesame, so that all the strips will be free to bend, and the strips 0 Cwill be free to slide lengthwise relatively to the others.

The holder O is provided with a socket D, which is provided with lugs (1(Z and a screw (Z whereby the socket maybe tightened and loosened atpleasure.

The type just described will have its printing-surface normally flat,and yet is of such construction that said surface may bend in alldirections to conform to a convex article.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. A type having a printing-surface, a sheet of flexible material withwhich it is connected, and a number of resilient strips of metalconneeted to said sheet, substantially as specified.

2. A type having a printing-surface, a sheet of flexible material withwhich it is connected, a number of resilient strips of metal connectedto said sheet, and a holder having arms with which such strips areconnected, substantially as specified.

3. A type having a printing-surface, a sheet 4. A type having aprinting-surface, a sheet of flexible material with which it isconnected, a number of resilient strips of metal C O C 0* andlongitudinally slotted at the end portions, a holder having arms 0,screwspassing through the slots of said strips and entering the arms ofsaid holder, and other springstrips C C, crossing each other oppositethe center of the said sheet, having slotted end portions, and screwspassing through these slotted end portions and connected With the strips0 C 0 0 substantially as specified.

Signed at New York, in the county of New 20 York and State of New York,this 12th day of May, A. D. 1890.

THOMAS HARPER.
